Entomopathogenic Fungi Biomass Production and Extracellular Biosynthesis of Silver Nanoparticles for Bioinsecticide Action

Entomopathogenic fungi are microbial agents of insect control in nature. They have been used as biologic strategies to manage invasion; however, the challenge is maintain their shelf life and viability when exposed high temperatures, ultraviolet radiation, humidity. Synthesized silver nanoparticles (AgNPs) from fungal extracellular enzymes an alternative using these microorganisms obtain with insecticidal action. The present study evaluates biomass production potential synthesize entomopathogenic isolates. Sixteen isolates were this study. pathogenicity virulence evaluated model Tenebrio molitor, at a concentration 5 × 106 conidia/mL. was produced liquid medium, dried, weighed. synthesis performed aqueous extracts nitrate solution (1 mM), following characterization by UV/vis spectrophotometer, mean size, polydispersity index. results showed significant variation pathogenicity, virulence, among isolates; only one did not nanoparticles. Pearson’s correlation values between biosynthesis potential, both negative values, indicating inverse correlation. Thus, AgNPs fungus extract can produce innovative bioinsecticide product green process.
